Beit known that I, JOSEPH BERK, n citizen v of the Unit-ed States, residing at ban ltranl-spring and release eiseo, in the county of Son Francisco and Stute of California, have invented new und useful Improvements in Hose-Couplings, it' whiel the following is o specification.

This invention rehites to improvements in hose-couplings, the object of the invention coupled.

being to provide zin improved form of hoseeoupling the members ot' which shall be inten changeable, so that the end ol any piece of hose furnished with one of sziid coupling members con be. immediately zitta-chad to the end of any other piece of hose so furnished,

very quickly zittuelied ond whirli will be strong and durable in oonstrurlion. v

' 1n the o'oeoiupiiiiyiiig drawing, Figure'l is a side View of the roupling members detart-hed. ["ig. L is ai sliniliir view oi` the sume lig. 3 is :i plain view ot' the coupling iiiein'bers detiiebed. View of the sumoroupled. big. 5 is a longitudiniil spi-tion ol the members coupled.

Referring to the driiwiiig,

forni und having ii terminal rib 2 for the purpose ol" retaining in position on siiid member the hose., (shown in dotted lilies zit 3.) The inner end of the coupling member is formed oblique .with the iixis of sziid member, :is shown :it 4. Overhnnging the retreating 'side of siiid oblique end isii semic-ylindriciil guide 5, t lie function of whieh is to guide into und li'old in position the projecting side ofthe oblique end of the opposite eouplingmen'iber. Dinnietrieolly opposite to ene-h other, one fit the center of' soid'giiido 5 zuid the other on the moin bod y l, tire two lugs 6, Viiround which aireseeured the ends of springs 7, eeh coinprisiiigii. eentriil loop S :uid coils 9, the, latter being for the purpose o'i furnishing iidditioniil .resilient-.y to the 'spi-ings. Onthe o posite side of oooh member from tlnit on w ieli the spring rests is formed ai short standard l0, upon which is pivoted nn iirin 11. Suid firm is iidiipted tro be inserted through the. loop of the spring on the op'posite 1neinber,-iiiid siiid through nearly two right ongles extend said springs so os to iirmly' eliim the two ooupling 'members together. spring is received between the base of the l 1 indicaties the body ol' the eoi'ipling member, cylindrical 1n urnis when turned' Tie loop of thev i l l l i i i l i l l i"ig. 4 1s o simihir- .the sides beimlr coiled i arm 11 .find a lip 12, the function of said lip being to positivelyv raise the loop of the it when the arm 1l is thrown boek to its original position. Elliptical rubber washers 13 are interposed between the ends of the members to make the coupling waiter-tight.

The operation of the device is veryA simple. The two coupling members are brought together, the. projecting part of the oblique en d of each entering the cylindrical guide of the opposite coupling member. In this position the loops of tliesprings will readily assume a position over oroutside of the larms 11, whereupon b v turning said varms, through nearly two right ingles the springs are extended, snd the eoupling members firmlyl eliimped Yhigether. It n'ill reiidihr be seen tlnit tlie tu o eoupling members being idontieiil in form eau-h nieiiilier'ezin quickly b e a'ttiiehed to coupling memlu, 's of like character on another pieeo of hose. Q

I eluiin- 1.. A bose-coupling, the two members whereof are identienl in form, euch Comprising o spring having u loop and n pivoted arm adopted to engage the spring of the opposite member und extend the same, substantially ns described..

2. A hose-coupling, the two members whereof ire identieiil in forni, ene-h comprising u. spring sittncbed'at its ends to the mempivoted'ar-m adapted to engage the spring of i the opposite. member and extend the same,

' 3. A4 hose-coupli g, tbe. two members whereof are identieiil in form, eiieh comprising u spring nt'tiiebed nt its ends to the member, the middle portion forming o. loo and and o pivote arm adapted to engnge the spring of the opposite member sind extend the stime, substantially as described.

4. AI hos'ocoupling, the two members whereof fire .identieul inform, eiieh compris? ing a spring having u. loop und o pivote-d armv adopted to engage tbe spring oiy the opposite extend the sume, said arm havengagey the. loop to release the the nrin is reversed, substanmelnber und vingn lip to spring when tially as described.

5.. A hose ooupling, the two members whereof are identical in form,I each comprising n. spring having a loop and a pivoted arm 1 In testimony-whereof I have hereunto set adapted to engage the spring of the opposite i my hand in the presence of two subscribing member and extend the same, each member witnesses.
